In the Middle Ages Nowy Jasiniec castle served as a border stronghold on the trade route from Polish to Pomesania. It was conquered and rebuilt by the Teutonic Order in the 14h century. During the wars between Teutonic Order and Poland it was destroyed and then rebuilt again in 1454. Between 1466-1772 Nowy Jasiniec was the seat of local lords. Between 1773-1846 the castle served as an evangelical church. Later it fell into disrepair and is today in ruins.
The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
